When you first purchase a monitor is comes with a driver, this driver helps your operating system for your computer understand your monitor and be able to communicate with it. But as time goes on your monitor tends to drift in terms to there calibration, for most people this isn’t a big issue. But if you are a photographer it is very important because when you edit your photographs on your monitor the output might not match to your printer. Over time this could be really far off. The only way to solve this problem is monitor calibration. There are numerous products out there to help you calibrate your monitor. They can be expensive but I found that LaCie, X-rite, and Pantone all make a great product for around $100. This is an article on how to calibrate your monitor
These products come with a “puck” that hangs in front of your monitor and plugs into your USB port and comes with software that walks you through the steps in calibrating your monitor.
Once your “puck” is placed properly on your monitor and you’re running your software. You will then be prompted to leave it alone and let it sample different colors on your Screen. Those colors get read into the puck and into the software.
You will then be asked to make calibration changes to your monitor. Most monitors have a setup button when you press the setup button on the monitor you come up with different kinds of options that you can change, including red, green, and blue settings or temperature and color settings.
Make fine changes to these colors, the puck on your monitor will resample your changes and come back and show you how accurate it is within a certain temperature range. Once you reach the desired temperature range you then calibrate it.
The software will now create a driver or applet that your operating system will load every time you turn your computer on. This driver is a custom driver that was developed by you calibrating software that will show accurate and true color. This means when you work on your photos and print them what you see on your monitor is what you will get. This was an ehow on how to calibrate your monitor.
